Patients Concern
Disease/Condition Glossary
Osteoarthritis: It is a degenerative joint disease in which the two ends of the joints come together due to the breakdown of a protective covering of cartilage. Without this protective covering, the joints rub against each other, leading to pain and stiffness. Symptoms of osteoarthritis include pain, stiffness, inflammation, and tenderness. The main reason for osteoarthritis is age; the older you are, the more likely you are to develop it, making it a degenerative disease, as the joints wear out as a person ages. Other reasons include a past injury such as torn cartilage, dislocated joints, and ligament injuries.
